Contact with liquid causes severe irritation of eyes and irritation of skin. Chemical readily penetrates skin in harmful amounts. Ingestion causes irritation of mouth and stomach. | [Potential Exposure]
Glutaraldehyde is used in leather
tanning; in embalming fluids; as a germicide; as a
cross-linking agent for protein and polyhydroxy materi als; as a fixative for tissues; and as an intermediate.
Buffered solutions are used as antimicrobial agents in
hospitals. | [Fire Hazard]
Literature sources indicate that this chemical is nonflammable. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
30 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [Shipping]

Glutaraldehyde is an effective protein crosslinker and finds application in techniques like enzyme immobilisation microscopy, histochemistry and cytochemistry. It exists in different forms under acidic or neutral conditions. It is a biocide widely used as a disinfectant in hospitals and industries and is toxic to aquatic organisms. Its allergic nature leads to hypersensitivity reactions. Contact of glutaraldehyde vapors in endoscopy contributes to Colitis. | [Purification Methods]
Likely impurities are oxidation products-acids, semialdehydes and polymers. It can be purified by repeated washing with activated charcoal (Norit) followed by vacuum filtration, using 15-20g charcoal/100mL of glutaraldehyde solution. Distil it at 60-65o/15mm, discarding the first 5-10%, then dilute with an equal volume of freshly distilled water at 70-75o, using magnetic stirring under nitrogen. The solution is stored at low temperature (3-4o), in a tightly stoppered container, and protected from light. Standardise by titration with hydroxylamine.
